The study of force control of servogun by using feedback current of the servo-motor

서보 모터의 피드백 전류를 이용한 서보건의 가압력 제어에 관한 연구

Force is one of the most important variables with welding current and welding time in resistance spot welding. But a good farce control method hasn't been come out on servogun resistance spot welding system. In this study, we prove the feedback current of the servo-motor can be used to an excellent force measuring sensor and the force can be also controlled by the feedback current.
